JOHN A. LEGGATT, OF HAMILTON, CANADA.

BOLT.

SPECIFICATION forming part of Letters Patent No. 500,111.3, dated .Tune2'?, 1893.

Application filed September 28, 1892. Serial No. 447,206. (No model.)v

To afZZ whom. it may concern,.-

Be it known that I, JOHN A. LEGGATT, a subject of the Queen of GreatBritain, residing at Hamilton, in the countyof Wentworth, inthe Provinceof Ontario, Canada, have invented a new and useful Door-Bolt, of whichthe following is a specification.

My invention relates to improvements in door bolts, in which a verticalbolt, provided with arubber tip, and incased in a metallic casing, isoperated and adjusted vertically by means of pressure by the foot on theupper end thereof, in conjunction with mechanism in the interior of saidcasing; andthe objects of my improvements are, first, to provide a boltcapable of being operated by the foot; second, to afford facilities forthe proper adjustment, with certain pressure, of the bolt, having rubbertip, to any position on the Hoor, when door is partially open; andthird, to provide means to retain said bolt in position of pressureagainst the door, or in an aperture, and to release the same. I attainthese objects by the mechanism illustrated in the accompanying drawings,in which- Figure 1 is a front elevation of the entire device, with threeparts broken away to show the interior. Fig. 2 is a sectional plan ofthe same, through the broken lines, w, m. Fig. 3 is a section throughthe broken lines, c, fn, having bolt removed. Fig. 4 is an enlargedsection through the broken lines, o, c, with its central bolt. Fig. v isa side elevation of the top of bolt.

Similar letters refer to similar parts throughout the several views.

The casing, A, having screw holes, a, is screwed to the lower part of adoor, H, as shown in Fig. 2. The bolt, B, as shown incased, is providedat its lower end with a rubber tip, cork, or material of like nature,indicated by c, which is inserted into said bolt. The upper part of bolthas a projection, D, which, when pressed downward by the foot, insertsthe lower end of bolt into an aperture in the oor, and wheny desirableto have the door partially open, then the rubber tip is used, withpressure against the door, in lieu of an aperture. To retain the bolt inthe ap- "erture, or-against the floor, the said projection, D, whenpushed downward by the foot, is, at the same time turned to either side,thereby engaging the thread, E, which is on two sides of the bolt, .withthe thread, F, of the base of casing, and the inner part, I, of cover,J. The section of the part of bolt having thread, is seen at Fig. 4,having two sides flattened. This thread extends from the shoulder, K, tothe shoulder, L. W'lien releasing the bolt from its pressure position,it is necessary to press the foot on the said upper projection, D, andat the same time bring it to a right angle to the door, and the spiralspring, S, will raise the bolt to its position as shown. The said springpresses against the partition, fm, of case and the collar, n, of bolt.The partially inclosed upper end,'n,, of casing, retains bolt inposition. It will be perceived, that that part of the bolt which isthreaded, is, when descending or ascending, entirely free, on account ofits flattened sides, but when turned to either side, it engages with thethreaded casing on the line, c, t, also with a portion of the cap atthis particular place. Bolts ot' this construction may be applied todoors, in an inserted manner, as well as on the face, when required,with only the foot projection protruding. Y

What I claim as my invention, and desire to secure by Letters Patent, is

The combination in a door-bolt, of a casing, A, provided with a slot,having partition, fm, partially inclosed upper end, fn', and a part ofthe inner base of casing, threaded as at F, the cover, J, threaded as atI, the bolt, B,hav ing projection, D, collar, n, and threaded at E, withtwo sides flattened, and the spiral spring, S, substantially asdescribed and set forth.

JOHN A. LEGGATT.
